Effects of the extern keyword on C functions
...ons, extern is not needed as it is on by default.
Note that the rules for C++ are different. For example, extern "C" is needed on the C++ declaration of C functions that you are going to call from C++, and there are different rules about inline.

What is the default location for MSBuild logs?
...
Log file from Visual Studio is only supported for C++ projects. You just have to work with the output window for others.
See this similar thread: VS2010: minimal build log in output and detailed log in log file
And in case you happen to do this for a C++ project, the file ...

Header files for x86 SIMD intrinsics
...der name depends on your compiler and target architecture.
For Microsoft C++ (targeting x86, x86-64 or ARM) and Intel C/C++ Compiler for Windows use intrin.h
For gcc/clang/icc targeting x86/x86-64 use x86intrin.h
For gcc/clang/armcc targeting ARM with NEON use arm_neon.h
For gcc/clang/armcc target...
throw new std::exception vs throw std::exception
...ception object and to catch it by reference (usually const reference). The C++ language requires the compiler to generate the appropriate code to construct the exception object and to properly clean it up at the appropriate time.
Throwing a pointer to a dynamically allocated object is never a good ...
Python naming conventions for modules
...
Windows versions, or DOS.
When an extension module written in C or C++ has an accompanying Python
module that provides a higher level (e.g. more object oriented)
interface, the C/C++ module has a leading underscore (e.g. _socket).

Override compile flags for single files
...when this source file builds.
You should be able to countermand the -Weffc++ flag for foo.cpp by doing
set_source_files_properties(foo.cpp PROPERTIES COMPILE_FLAGS -Wno-effc++)
This should have the effect of adding -Wno-effc++ after -Weffc++ in the compiler command, and the latter setting wins....
Are Java static calls more or less expensive than non-static calls?

Mutable vs immutable objects
... course that you're using a language which makes this a tenable opinion (C/C++ makes this very difficult, as does Java). In short: the advantages depend somewhat on your problem, but I would tend to prefer immutability.

Technically, why are processes in Erlang more efficient than OS threads?
...ystem. That's really what's wrong with programming languages like Java and C++. It's threads aren't in the programming language, threads are something in the operating system – and they inherit all the problems that they have in the operating system. One of the problems is granularity of the memor...
